Timing the needle

breaking needles from hitting can be from several problems
1-- needle /hook timing is out
2--needle thread tension is too tight pulling needle side ways
thread caught around bobbin holder is top thread too loose
take it in for a service check as the needle /hook timing is complicated to adjust and the problem could be more complicated than suggested

remove the cover over the bobbin section so that you can see the needle bobbin carrier interaction
now turn the machine over by hand and watch the needle go down and start to come up
at this point the hook of the bobbin carrier should be very close to the needle just above the eye of the needle
It is at this point the the needle thread is picked up and run around the bobbin carrier to link up with the bobbin thread
if it is not there then take it in for an adjustment as the adjustment is done by loosening off the clamp on the vertical bar at the end of the machine that moves the needle up and down and positioning the needle in the position described
if the needle is hitting the bobbin and the timing is correct , replace the needle as it may be bent or not in properly

The hook timing is probably off. Needs to go in to the shop.

Hook/needle timing needs a hands on guidance to get it fix, 2 options either you can watch in utube 'singer sewing machine hook timing' or 'google' for singer 7469q service manual for your referral.

Sounds like it's advanced.... but take it in and have it done professionally... have him lube and clean and check for cracked parts while you are at it.

you can try changing the needle
but it sounds like the machine is out of time & needs to be checked for
timing issues & also to see if the needle bar is bent or damaged & to
see if the feed dogs are out of time or just need a adjustment

If this is a drop-in/horizontal bobbin, raise the needle to it's highest position. Remove the bobbin case then replace it so it fits snugly into the shuttle. Hand walk to see if the case moves freely in a circle. If it stops, it is not positioned correctly. You do not have to have a needle in to test this.

Once you are sure the bobbin case is correctly in place, re-install the needle. Hand Walk to make sure the case turns without any interference.

If the needle continues to hit, then the machine needs to go into the shop for service.

There is a DIY for adjusting the timing of the hook sewusa.com if you wish to try the adjustment on your own.

This is a timing problem the hook timing needs adjustment, and possible the needle timing also

Your timing is off. There should be a ruber belt behind your hand wheel, if you take off the case around it; you should be able to adjust your timing of the bobbin casing.

Is the needle inserted correctly with the flat side at the rear and fully up into the holder ?

If yes, take off the needleplate, remove bobbin case and slowly rotate the handwheel towards you watching the relationship between needle, and the "hook" of the moving "race".

Set on wide zig zag........when the needle is fractionally past it's lowest point, and starting to rise, the hook should be level with the left side of the needle when on the right hand stitch of the zig...the eye of the needle will be below the hook, and ready for thread to be picked up for the stitch to form.

Any other result will mean your timing needs adjusting.
